Title: Centralized oil control system
Inventor: SASAKI TOORU
IPC: F16C39/00
Filed: 1980-02-28
Abstract: PURPOSE: To realize a saving of resources and energy by carrying out the purification of machine oil, removal of moisture and supply of oil only by a valve operation.  
     CONSTITUTION: When the moisture within an oil tank TK 1  is removed, valves A 1 , P 1 , P 2 , P 5  and B 1  are opened whereas the other valves are closed to drive a pump PP. The oil flows from the oil tank TK 1  through the pump PP and moisture removing device DH returning to the oil tank TK 1 . Similarly, when only an electrostatic purification is performed, valves A 1 , P 1 , P 3 , P 6  and B 1  are opened with the other valves closed, so that the oil flows through an electrostatic oil purifying tank EDT. In order to make a treatment to the other oil tanks TK 2  to TK 10  or an auxiliary oil tank a, it is sufficient to carry out a similar valve operation.

Title: Screen residue squeezing screw press
Inventor: SHINOHARA SUSUMU
IPC: E02B5/08
Filed: 1994-01-27
Abstract: PURPOSE:To squeeze screen residue completely and prevent clogging by providing a hopper into which screen residue is thrown, a screw body and a dewatering head, and providing the dewatering head with a pressing plate and spring mechanism. CONSTITUTION:Screen residue is thrown into a hopper 1, and a current is applied to a motor 5 to rotate a screw body 6. The screen residue 5 is thereby fed in the direction of a discharge port 8 and squeezed and dewatered at a tapered part 16. The dewatered residue having passed the tapered part 16 is then pushed out onto a squeezing gutter 13. At this time, the dewatered residue advances pushing up a pressing plate 14 pressed by the resilience of a coil spring 32. The water content of the preceding dewatered residue pushed by the succeeding dewatered residue is reduced to the extreme degree, but since the pressing plate 14 pressed by the resilience of the coil spring 32 is pushed up by strong force, the cross-sectional area of an outlet is enlarged in proportion to squeezing, so that the dewatered residue is discharged without hindrance. Structure and maintenance are thereby simplified, and the residue can be squeezed even more remarkably by plural screw bodies 6.

Title: Liquid vessel
Inventor: SAKURADA MASATAKA
IPC: B65D83/00
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To reduce a residual amount of content after extraction of e.g. a high viscous liquid by making the depth from the flange part of an upper vessel to the bottom plate larger than the depth from the flange part of a lower vessel to the bottom plate, and forming radially ribs on the bottom plate of the lower vessel from the proximity of an extraction port to its periphery. SOLUTION: Depths of an upper part vessel 20 and a lower part vessel 21 are lying in the range of 1.0-1.2 times in a state where the depth from a flange part 23 to a bottom plate 22 is larger than the depth from a flange part 13 of the lower part vessel in a condition of the upper part vessel with exterior forces exerted. Besides, on the bottom plate of the lower part vessel, linear ribs 15 projected from the surface of the bottom plate are formed radially from the part near an extraction port 14 to its periphery.  With extraction of the content, even if the upper part vessel depends on, it is supported by the ribs radially formed from the proximity of the bottom plate-shaped extraction port of the lower part vessel so as to prevent the extraction port from being clogged due to the upper part vessel, thus ensuring a passage of the content toward the extraction port from its periphery along the ribs.

Title: Reader
Inventor: IWATA MASAAKI
IPC: G06K7/10
Filed: 1989-02-06
Abstract: PURPOSE:To shorten an optical path from a light source to an information medium and to make a reader compact by providing a correcting means to correct the waveform of an electric signal to be transferred to a decoding means. CONSTITUTION:The correcting means is composed of a corrector 11 and infrared light emitter/receiver 9. A binarization signal 5, for which the left marging part of information 8a is lacked, is outputted from a light receiving part 5. Then, since this signal is inputted to an OR circuit 14, the OR circuit 14 synthesizes and corrects waveforms 7 and 8 and the synthesized and corrected waveform is outputted to a decoding means 12 as a correct waveform 6. Here, the information 8a is decoded. Thus, since the waveform outputted from the light receiving part 5 is corrected, the optical path from a light source 4 to an information medium 8 is shortened and the reader is miniaturized.

Filed: 1986-02-10
Abstract: PURPOSE:To surely protect the secret of software with respect to the 3rd party by substantially destructing an internal circuit so as to disable the function of the circuit if one or several dissidences of a password are found. CONSTITUTION:A comparator circuit CMP compares a password which is stored in a ROM and read out to a data bus with an input signal supplied from a specific external terminal, and decides coincidence or dissidence of them. A counter circuit counts a dissidence output, and a boosting circuit VG operates if the number of said outputs becomes plural. The circuit VG forms a higher voltage than a power source voltage VCC, and generates a boosting voltage VCC' producing a latchup in an internal CMOS circuit. The action of the boosting circuit VG develops a latchup in the CMOS internal circuit including an important function comprising one chip microcomputer, whereby the circuit is destructed.
